Brodmann area 35, together withBrodmann area 36, comprise theperirhinal cortex. They arecytoarchitecturally definedtemporal regions of thecerebral cortex.

Human Brodmann area 35

[edit]

This area is known asperirhinal area 35. It is a subdivision of thecytoarchitecturally definedhippocampal region of thecerebral cortex. In the human it is located along therhinal sulcus. Cytoarchitectually it is bounded medially by theentorhinal area 28 and laterally by theectorhinal area 36 (H).

Monkey Brodmann area 35

[edit]

Brodmann found a cytoarchitecturallyhomologous area in the monkey (Cercopithecus), but it was so weakly developed that he omitted it from the cortical map of that species (Brodmann-1909).

Brodmann area 36

[edit]

With its medial boundary corresponding approximately to therhinal sulcus it is located primarily in thefusiform gyrus. Cytoarchitecturally it is bounded laterally and caudally by theinferior temporal area 20, medially by the area 35 and rostrally by thetemporopolar area 38 (H) (Brodmann-1909). Its function is part of the formation/consolidation and retrieval ofdeclarative/hippocampalmemory[1] amongst others for faces.[2] There is also evidence that area 36 may be associated with emotion regulation.[3]
